Grip an overhead pull-up bar with your hands just wider than shoulder-width, using an overhand grip.
Allow your body to hang freely, with arms fully extended and shoulders relaxed — this is the dead hang position.
From this position, engage your shoulder blades by pulling them down and slightly back towards your spine, lifting your chest gently upwards without bending your elbows.
Hold the top scapular retraction for a brief pause, focusing on squeezing the muscles between your shoulder blades.
Slowly relax back into the dead hang position with control.
Complete repetitions as prescribed by your physiotherapist.
